Abstract
The invention consists of a first lens barrel in which the first group of lens is mounted, an image sensor, a second lens barrel in which a holding unit and a second group of lens are mounted, and a reflector. The second lens barrel joints with first lens barrel in a certain angle to make light beam shot to the second barrel via first lens barrel. The reflector sits at the joint between first lens barrel and second lens barrel. The image sensor sits behind the second group of lens. The invention sets up lens groups along vertical and horizontal direction so that thickness of digital cameral can be reduced.
Description
[technical field]
The invention relates to a kind of digital camera of thinner thickness.
[background technology]
Digital camera is the novel product in conjunction with optics, precision optical machinery and electronics technology, and is convenient because it is taken, and need not flushing after clapping, thereby becomes the electronic installation of the outdoor travelling indispensability of people.For ease of carrying, people wish little, the light weight of the volume of digital camera.
The structure of traditional digital cameras comprises: a lens barrel, a filter, an Image Sensor.A plurality of eyeglasses are housed in this lens barrel, and a plurality of eyeglasses are positioned on the same optical axis.This filter is positioned at after a plurality of eyeglasses, and Image Sensor is positioned at after the filter.A plurality of eyeglasses, filter, Image Sensor all are positioned on the same optical axis, so depend on the thickness of this direction assembly on the big extremely degree of camera thickness.In order to reduce the thickness of camera, adopt the method that reduces eyeglass quantity to reduce axial thickness usually.Eyeglass reduces must satisfy again simultaneously image quality preferably, so the normal aspherical lens that adopts reduces eyeglass quantity in the prior art.For the low order digital camera, the minimizing of eyeglass quantity can make the reduced thickness of camera, but for the high-order camera, as the digital camera more than eight mega pixels, for satisfying imaging requirements, the eyeglass number needs meets certain requirements, could guarantee image quality preferably, therefore, along with the raising of digital camera pixel, the also corresponding increase of the axial width of digital camera, thereby requirement that can not the digital camera miniaturization.
In view of above shortcoming, be necessary to provide a kind of thin type digital camera that reduces digital camera thickness.
[summary of the invention]
The object of the present invention is to provide a kind of digital camera of thinner thickness.
The present invention discloses a kind of thin type digital camera, comprise: one first lens barrel, one Image Sensor, in described first lens barrel first lens set is housed, this thin type digital camera also comprises one second lens barrel and a reflection unit, and this second lens barrel comprises a holding part and second lens set, and this holding part is in order to ccontaining second lens set, described second lens barrel is with first the lens barrel axis is angled links to each other, and makes light be mapped to second lens barrel from first lens barrel; Described reflection unit is positioned at first lens barrel and the second lens barrel junction, and described Image Sensor is positioned at after second lens set.
Compare prior art, the present invention is provided with different lens set in two vertical direction, and with reflection unit light is directed to second lens set from first lens set, thereby the Z that has reduced camera has satisfied the requirement of digital camera thin typeization to thickness.
[description of drawings]
Fig. 1 is a thin type digital camera structural representation of the present invention.
[embodiment]
See also Fig. 1, thin type digital camera of the present invention comprises first lens barrel 10, second lens barrel 20, spectroscope 30, infrared fileter 40, Image Sensor 50.
First lens barrel 10 is cylindric, and first lens set 12 is housed in it, and this first lens set 12 is made up of a plurality of lens, and it at first contacts the light that enters camera by the external world and simultaneously light is converged.This first lens barrel 10 is positioned on the Z-direction, for protecting first lens set 12, is provided with glass plate 14 before this first lens set 12, and this glass plate 14 makes it avoid scratch in order to protect first lens set 12, also can avoid dust to enter simultaneously.
Second lens set 22 is equipped with in second lens barrel, 20 inside, and this second lens set 22 is made up of a plurality of lens.This second lens barrel 20 comprises a holding part 24, a junction 26, a base plate 28.This holding part 24 is positioned on the X-direction, in it in order to loading second set of lenses 22, thereby make the optical axis of first set of lenses 12 and second set of lenses 22 vertical mutually.Connecting portion 26 is positioned at an end of holding part 24, and this connecting portion 26 is positioned on the Z-direction, and it is threaded with first lens barrel 10, and connecting portion 26 communicates with first lens barrel 10.This base plate 28 is positioned at the other end of holding part 24, and relative with connecting portion 26.
This spectroscope 30 is placed in second lens barrel 20, and is positioned at the junction of first lens barrel 10 and second lens barrel 20.This spectroscope 30 can be with the light that converged by first set of lenses 12 in spectroscope 30 reflexes to second set of lenses 22.
Filter 40 at least one coating surface one deck IR-cut filter membranes (IR-cut Coating) come from the infrared ray in the light of object reflection, thereby improve image quality with filtering.This filter 40 is positioned at after second set of lenses 22, also can protect Image Sensor 50 simultaneously.
Image Sensor 50 can be charge-coupled device (Charge Coupled Device calls CCD in the following text), perhaps complementarity matal-oxide semiconductor (Complementary Metal-OxideSemiconductor calls CMOS in the following text) usually.This Image Sensor 50 is positioned at after the cutoff filter 40 and is fixed on the base plate 28 of second lens barrel 20, and it is in order to change the light signal into electric signal.
During work, from the light of subject reflection through first lens set 12, this first lens set 12 converges light, and cause second lens set 22 through spectroscope 30, again through filter 40, infrared ray in the light is filtered, on Image Sensor 50, change the light signal into electric signal at last, thereby finish shooting process.Unclear or the focal length of image can not meet the demands if be taken, and can make it change distance between first lens barrel 10 and second lens barrel 20 by manually rotating first lens barrel 10.
In another embodiment of the present invention, this thin type digital camera also may be used in the portable electron devices such as mobile phone, only need base plate 28 is saved, and make second lens barrel, 20 these ends is open end, and Image Sensor 50 is connected with the printed circuit board (PCB) of mobile phone, and other assembly is identical with above-mentioned execution mode.The mobile phone of this tool thin type digital camera can reduce the thickness of Z-direction, and makes full use of the length of the X-direction of mobile phone, thereby satisfies the requirement of mobile phone miniaturization.
Be appreciated that spectroscope 30 also reflection unit such as available level crossing replace, thereby the light beam of Z-direction is changed over the light of X-direction.
First lens barrel 10 also can become other angle to link to each other with second lens barrel 20, and its connected mode can be fixedly connected or is slidingly connected, and whether this needs according to camera is tight shot or zoom lens decision.If tight shot, first lens barrel 10 and second lens barrel 20 can be one of the forming, and also first lens barrel 10 and second lens barrel 20 can be fixed by a glue, achieve a fixed connection.If zoom lens can be arranged to be slidingly connected at first lens barrel 10 and second lens barrel 20, thus the distance of adjusting Z direction; Also the connecting portion 26 of second lens barrel 20 can be separated with second lens barrel 20, making second lens barrel 20 is open end with base plate 28 relative ends, and therefore this open end and connecting portion 26 when needs adjustment focal length, also can adjust the distance of directions X for being threaded.
